DE RecName: Full=Peptide chain release factor 1 {ECO:0000255|HAMAP-Rule:MF_00093}; DE Short=RF-1 {ECO:0000255|HAMAP-Rule:MF_00093}; GN Name=prfA {ECO:0000255|HAMAP-Rule:MF_00093}; GN OrderedLocusNames=RBE_0298; OS Rickettsia bellii (strain RML369-C). OC Bacteria; Pseudomonadota; Alphaproteobacteria; Rickettsiales; OC Rickettsiaceae; Rickettsieae; Rickettsia; belli group. OX NCBI_TaxID=336407; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=RML369-C; RX PubMed=16703114; DOI=10.1371/journal.pgen.0020076; RA Ogata H., La Scola B., Audic S., Renesto P., Blanc G., Robert C., RA Fournier P.-E., Claverie J.-M., Raoult D.; RT "Genome sequence of Rickettsia bellii illuminates the role of amoebae in RT gene exchanges between intracellular pathogens."; RL PLoS Genet. 2:733-744(2006). CC -!- FUNCTION: Peptide chain release factor 1 directs the termination of CC translation in response to the peptide chain termination codons UAG and CC UAA. {ECO:0000255|HAMAP-Rule:MF_00093}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00093}. CC -!- PTM: Methylated by PrmC. Methylation increases the termination CC efficiency of RF1. {ECO:0000255|HAMAP-Rule:MF_00093}. CC -!- SIMILARITY: Belongs to the prokaryotic/mitochondrial release factor CC family. {ECO:0000255|HAMAP-Rule:MF_00093}.
